Description

Technical Field

[0001] This invention relates to an ear cleaner, specifically to the field of personal ear canal cleaning and care devices, and more specifically to an ear cleaner that uses fluid-driven local expansion and has an internal and external air pressure balance function. Background Technology

[0002] Ear canal cleaning is an important part of daily personal hygiene. Currently, common ear canal cleaning tools on the market mainly include traditional hard ear picks and electronic visual ear picks. Traditional hard ear picks have hard tips that can easily scratch the ear canal skin during use and cannot adapt to the curvature of different ear canals, posing a significant safety hazard. Electronic visual ear picks have complex structures, require charging, and are expensive, and the tips are still made of hard materials, failing to fundamentally solve the safety problem of hard materials contacting the ear canal wall. Existing technology has developed cleaners that use an air bladder to inflate the head and fit against the ear canal wall. However, these products generally have the following drawbacks: the inflated head completely seals the ear canal, creating negative pressure inside the ear canal when the user removes it. This negative pressure acts directly on the eardrum, potentially causing pain or even eardrum damage; furthermore, these products are mostly multi-part assembly structures, resulting in high manufacturing costs and poor sealing. Therefore, this invention proposes an improved ear cleaner to solve the above problems. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an ear cleaner that uses fluid pressure to drive local expansion to conform to the ear canal wall for cleaning, and maintains pressure balance inside and outside the ear canal through a through-channel when removed, thus eliminating the risk of ear injury from negative pressure.

[0004] (II) Technical Solution To achieve the above objectives, the technical solution adopted by the present invention is as follows: an ear cleaner, comprising an airbag body, wherein the airbag body is a hollow shell with a sealed cavity inside, and a fluid medium is encapsulated within the sealed cavity. At least one end of the airbag body has an extension portion, which communicates with the internal cavity of the airbag body. The extension portion has a thin-walled region, the wall thickness of which is less than the wall thickness of other regions of the extension portion, forming a radially expandable expansion portion. The ear cleaner has a through-pressure relief channel extending axially from one end of the ear cleaner to the other end, connecting the external atmosphere of the airbag with the internal space of the ear canal. The through-pressure relief channel is not connected to and is isolated from the internal cavity of the airbag body. When the airbag body is pressed, the fluid medium is pressurized, driving the thin-walled region to preferentially expand radially; when the airbag body is released, external air enters the ear canal through the through-pressure relief channel, counteracting the negative pressure generated during removal. Preferably, the airbag body is made of a flexible material. Preferably, the airbag body is a one-piece molded structure or composed of multiple sealed components. Preferably, the fluid medium is a gas, liquid, or colloid. Preferably, both ends of the airbag body have extensions. Preferably, the outer wall of the extension has a raised structure. Preferably, the raised structure is one or more combinations of threaded protrusions, spiral protrusions, or annular protrusions. Preferably, the outer wall of the extension is a smooth curved surface. Preferably, both ends of the airbag body have extensions, with one end of the extension having a raised structure on its outer wall and the other end having a smooth curved surface on its outer wall.

[0005] (III) Beneficial Effects Compared with the prior art, the present invention provides an ear cleaner with the following beneficial effects: First, by setting up a through-flow pressure relief channel, the inside and outside of the ear canal are always connected. When the ear is removed, external air enters the ear canal through the through-flow pressure relief channel to counteract the negative pressure, eliminating the risk of ear injury from negative pressure, making it safe and reliable to use.

[0006] Secondly, by setting a thin-walled area with a wall thickness smaller than other areas in the extension, when the airbag is squeezed, this thin-walled area will preferentially expand radially to fit the ear canal wall, thereby achieving directional expansion control, resulting in good cleaning effect without damaging the ear canal skin.

[0007] Third, it has a simple structure, can be molded as a whole or assembled in parts, is compatible with a variety of production processes, has low cost, and is suitable for large-scale production. Attached Figure Description Figure 1 This is a schematic diagram of the overall appearance of an ear cleaner according to the present invention. Figure 2 This is a schematic diagram of the working state of an ear cleaner according to the present invention (the expansion part expands radially to fit against the ear canal wall). Figure 3This is a cross-sectional structural diagram of an ear cleaner according to the present invention (showing the through pressure relief channel, the sealed cavity and the isolation relationship between the two). The meanings of the markings in the attached diagram are as follows: 1. Airbag body; 2. Protruding expansion part; 3. Curved expansion part; 4. Through-flow pressure relief channel; 5. Fluid medium. Detailed Implementation

[0008] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0009] Example 1. Figures 1 to 3 As shown, this invention provides an ear cleaner, including an airbag body 1. The airbag body 1 is a hollow shell made of flexible material, with a sealed cavity inside, which encapsulates a fluid medium 5. The fluid medium 5 can be a gas, liquid, or colloid, all of which can achieve the purpose of this invention. At least one end of the airbag body 1 has an extension portion, which communicates with the internal cavity of the airbag body 1. The extension portion has a thin-walled region, the wall thickness of which is less than the wall thickness of other regions of the extension portion, thereby forming a radially expandable expansion portion. When the internal pressure of the airbag body 1 increases, the thin-walled region, due to its smaller wall thickness and lower stiffness, preferentially deforms, achieving radial outward expansion. The outer wall of the extension portion may have a protruding structure, forming a protruding expansion portion 2, used to enhance the cleaning effect when expanding and conforming to the ear canal wall. The protruding structure can be one or more combinations of threaded protrusions, spiral protrusions, or annular protrusions. The outer wall of the extension portion may also be a smooth curved surface, forming a curved expansion portion 3, suitable for users who are sensitive to touch. The ear cleaner has a through-pressure relief channel 4, which runs axially from one end of the ear cleaner to the other, connecting the external atmosphere of the airbag with the internal space of the ear canal. The through-pressure relief channel 4 is not connected to and is isolated from the internal sealed cavity of the airbag body 1. During use, the user inserts the expansion part into the ear canal and presses the airbag body 1. The internal fluid medium 5 is pressurized, driving the thin-walled area to expand radially outward, causing the expansion part to conform to the ear canal wall. The ear cleaner is then rotated or pulled out to complete the cleaning. After cleaning, the airbag body 1 is released, and external air enters the ear canal through the through-pressure relief channel 4, counteracting the negative pressure generated during removal due to volume changes.

[0010] Example 2. The difference between this example and Example 1 is that both ends of the airbag body 1 have extensions. One end of the extension has a raised structure on its outer wall, forming a raised expansion portion 2; the other end has a smooth curved surface on its outer wall, forming a curved expansion portion 3. Users can choose to use different ends according to the sensitivity of their ear canal and their cleaning needs. The remaining structure and working principle are the same as in Example 1, and will not be repeated here.

[0011] Example 3. The difference between this example and Example 1 is that the airbag body 1 is a structure composed of flexible material components injection molded and sealed together, rather than a one-piece structure. The components are sealed together by adhesive, heat sealing, or snap-fitting to ensure the airtightness of the sealed cavity. The pressure relief channel 4 can be formed by pre-drilling through holes or embedding tubing during assembly. The remaining structure and working principle are the same as in Example 1, and will not be repeated here. It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and structure of the invention, the scope of which is defined by the appended claims and their equivalents.
